https://devzone.nordicsemi.com/f/nordic-q-a/122406/channel-souding-subeventI am trying to use the HCI UART application with channel sounding enabled and communicating with an external host. I was able to perform all CS procedures, and when it was time to receive the CS subevent result, I only received it once, followed by aen-USTelligent Community 13Fri, 20 Jun 2025 06:55:22 GMThttps://devzone.nordicsemi.com/thread/539956?ContentTypeID=1Fri, 20 Jun 2025 06:55:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7f837954-8675-42bf-88ad-3b79208175c0Abhinav152<p>Hi , Thanks for the prompt response. I was setting wrong param conigration , and procedure interval was invalid , now its working as expected</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/539952?ContentTypeID=1Fri, 20 Jun 2025 06:16:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ad0b04ed-2e1d-42e2-b1ba-c1b57a9c8594zhuxi<p>nordic demo is enable procedure one by&nbsp; one , so the code set the procedure count to 1. For you using cs in hci uart, you need to change the procedure count to zero or other value bigger than 1. If you already do these above, than check subevent&nbsp; procedure status to check whether abort happened, it may caused by too small&nbsp; procedure interval.</p><div style="clear:both;"></div>
